FFmpeg: Ticket #1587: Problem while reencoding .ass subtitleshttps://trac.ffmpeg.org/ticket/1587
<p>
Summary of the bug: When I'm reencoding softsubbed mkv files, with .ass subtitles, in some cases some formatted subtitles are disappearing, I've cut out a sample from a file, so it should be simple to reproduce the error.
I'll include the original file, and the reencoded file, so you can see the difference, the problem occurs at 0:02.

How to reproduce:

I've uploaded the files to the MPlayer FTP server, as they're 5 mb, and can't be attached, I hope it's ok, as I read that the sample files should be under 10 mb, and I couldn't make it under 5 mb.
They are called:
</p>
<ul><li>ass_subtitles_disappearing_Original_file.mkv
</li><li>ass_subtitles_disappearing_Encoded_file.mkv
</li></ul>

I cannot find the samples you mention in incoming, could you upload them again?
(There is no size limit, just upload as much as is necessary to reproduce the problem.)

Sorry for the late reaction!
